ROSIBAOK COM IPANY, OF BENTON HARBOR, MICHIGAN V STITCHING MACHINE The main objects of this invention are:

, First, to provide in a, stitchingmachine an improved combineddischarge and stack- 7 ingmechanism which is readily adapted or I; adjusted to work of varying dimensions. 7

Second, to provide a delivery mechanism for stitching machines which is of very large capacity. a v

Objects relatingto details and economies of my invention will appear from the description to follow. The invention is defined and pointed out in the claims,

The structure illustrated in the 'panying drawings embodies the work feeding and stitcher features of the structure illustrated in my said'application for Letters Patent, Serial No. 247,062.

. c am] being dellvered thereto by means' not illu'strated. The work is fed through the stitcher 'meral llare not described. The stitcher by means of the feed'rollers 4 and 5, the.

roller 5 being mounted for oscillatingmovement to and from work engaging position.

The means for effecting this are described in detail in my said application for Letters Patent and as they form no part of this invention are not described herein, the same however being partially, illustratedtin Fig. 8 and designated generally by the numeral 6.

The work is delivered by the stitcher feed rollers to the discharge conveyor, the-subject matter ofjthis application. This dis charge conveyor consists of a plurality of r idler supporting rollers 7, the journals f which are selectively engageable with notchlike bearings9 in the spaced horizon-tally disposed bars 10.

and'l4 are provided to coact with'certain of the idler rollers, the driving roller 11 being the first in the series and means are provided for controlling it whereby itis swung intoported in housings 16 connected by suitable A plurality of driving rollers ll, 12, 13.

gearing, not illustrated, to the shaft 17, the i housings and the gear ontheshaft having a sliding key connection thereto so that these rollers maybe adjusted relative to each other by sliding their housings along'o'rithe The housings for these feed rollers are supporting bar 18 extending longitudinally of the machine, the housings being provided with adjustable screws 19 which constitute stops or rests. These supports areprovided lo with thumb nuts 20 for retaining them in their adjusted positions.

To hold the pamphlets firmly and at the same time yieldingly to the stapling table as they are delivered to the stapling feed means and also as they are delivered from such means, I provide a brush 21 which is supported above the saddle-shaped 530 table so as to engage the work as it is fed thereto and moved along thereon. This brush also holds the work down as it is de livered to the first discharge conveyor feed roller 11.

The work is held to the supporting rollers by means of the depending guide fingers 22 and 23 which are inclined downwardly and rearwardly atthe sides of the supporting rollers. The work is discharged from the rear feed roller 14: into a coacting pair of vertical delivery rollers 24, a supporting plate 25 projecting rearwardly in alignment with the roller 7 so that the pamphlet is delivered in a vertical position onto the stacking table 26. As the work is engaged and moved forward by these rollers 24:, it is drawn between the guide plates 125, these plates having vertical parallel portions at their rear ends and forwardly diver, portions at their front ends. The guide plates 125 are provided with a spring stop 126 (see Fig. 11) which swings out of the path of the work as it is discharged through the throat provided by these guide plates and effectively prevents rebound thereof.

The stacking table 26 is provided with a central plate 27 disposed in alignment with the discharge conveyor. At its front end. the stacking table is provided with pairs of spaced bars 28 which are carried by brackets 29 slidable on the vertical supporting rods 30, the brackets being secured in their adjusted position by means of thumb screws 31.

The stacking table is provided with a pair of stop bars 32 mounted on the brackets or uprights 33, these brackets being adjustably secured to the edge of the table. The brackets are vertically slotted at 3 and 35 to receive the supporting bolts 36 for the stop bars so that the stop bars may be adjusted vertically on their supporting brackets and adjusted relative to each other.

The reciprocating gate-like plunger 37 is mounted to reciprocate back and forth across the plane of delivery of the work. Thi. plunger is made up of end uprights and spaced horizontal bars so that the stop bars 32 may be arranged between the bars of the plunger. The plunger 37 is provided with a base bar 38 which is carried by slides 39 supported at one end by the rollers 40 and at the other end by the pinions ll mounted on the bed 42 of the table-sce Fig. 8. The pinions 41 are mounted on a shaft 43 so that they are rotated together and thereby serve as an equalizing means for the plunger.

The plunger is connected by the pitInen to a crank 45 on the upper end of the shaft 46, this shaft 46 being driven from a shaft 47 disposed longitudinally of the machine and having suitable driving connection to the stitcher driving mechanism indicated generally by the numeral a8.

The stacking table is supported on a pedestal l9 having a rack 50 coasting with a pinion, not shown, mounted on the shaft 51 having a hand wheel 52.

The shaft d6 is mounted on a bracket 53 carried by the table bed so that the shaft is adjusted vertically with the table.

The work is deli ered by the plunger against the supports 5% weighted at 55 and slidable on the stacking table, a series of pieces of work 56 being indicated in Fi e.

10. To prevent the return of tie with the plunger and 'to hold it in upri ht position, the stop bars'32 and the bars 28 are provided with detents 57, these detcnts having offset inner ends 58 engaged with tongues 59 struck up from the bars, the 'detcnts being held in position by the springs 60 mounted on screws 61 to engage the detents near their inner ends. The detents have bill portions 62 arranged through holes 63 formed in the bars, as snown in 10, so that as the pieces of work are successively delivered, they are engaged by these detents and retained there- The-edges of the center plate 27 also serve to prevent the return of the work; that is, should the lower end of a piece of work slide towards the plunger,-it engages the edge of this plate which supports it so that the next stroke of the plunger will pull back to position against the pieces of work previously delivered.

@wing to the varying thickness of the work, the rollers 24 are supported on the shafts 64: by hangers 65 slidably mounted on the rods 66. The inward movement of these hangers is limited by the conical stop 67 mounted on the threaded support 68 disposed vertically between the hangers, the hangers being provided with inclined stop faces 69 coacting with the stop The coiled springs 70 hold the hangers yieldingly against the stop.

The shafts (E i are provided with beveled pinions 71 coacting v. th the beveled pinions 72 on a shaft 73 disposed parallel with the supporting rods 60. This shaft 73 is provided with a beveled pinion 7a meshing with a beveled pinion 75, shown by dotted lines in 2, on the shaft 17.

With this arrangement, the parts are all driven in synchronism, the plunger 38 being reciprocated at such speed that the panephlets or work are delivered, first on one side thereof and then on the other, so that the work is stacked on the table intwo stacks.

The first discharge conveyor feed roller. 7

11 is raised and lowered into and out of engagement with the work in timed relation to the delivery of the work from the stapling feed rollers. The mechanism illustrated consists of the arm 76 connected to the housing of the feed roller 11, this arm being connected by a link 77 to a lever 78 operated from the feed roll oscillating mechanism 6. This results inth'e operating of the first discharge conveyor feed roller and the stitcher' feed roller in proper timed relation; that is, they are oscillated to and from is believed that this disclosure will enable j the combmation of a plurallty of work supthose skilled in the art to embody or adapt my improvements as may be desired.
